TURBINE.

Specification of Letters Patent.

Patented Oct. 15, 1912.

Application filed March 12, 1912. Serial No. 683,327.

To all wiz-0m t may concern:

Be it known that I, WILLIAM ANDERSON, a citizen of Norway, residing' at Parkland, in the county of Pierce and State of Washington, United States of America, have invented certain new and useful Improvements in Turbine-Engines, of which the fol lowing is a specification.

This invention relates to improvements in turbine engines, its primary object being .to provide a simple and compact enginecapable of developing the maximum amount Vof power in proportion to the amount of pressure medium utilized.

Specifically, the engine herein described is constructed for use of steam as 'the pressure medium, and it is contemplated to use the steam thrice in producing the power before itis nally exhausted, the parts of the driving mechanism so cooperating as to aiford much power and use a small amount of steam.

While I have illustrated the preferred construction for using steam as the pressure medium, it will be evident that other mediums may be utilized with equally good re sults.

For a full understanding of the present invention, reference is to beV had to the following description and the accompanying drawings, in which Figure 1 is a longitudinal sectional view showing the driving elements in elevation, said section being taken approximately on the line 1 1 of Fig. 3; Fig. 2 is a similar sectional view on the line 2 2 of Fig. 3'; Fig. 3 is a transverse sectional view on the line 3 3 of Fig. 1; and Fig. A is a transverse sectional view on an enlarged scale through the revolving member, taken about Von the line 1 4 of Fig. 2.

Throughout the following detail description and on the several gures of the drawings, similar parts are referred to by like reference characters.

Referring to the drawings and specifically describing my invention, an engine constructed in accordance therewith comprises an outer casing or housing A supported on suitable standards B constituting a base, one of the sides of the casing, designated as A, being removably secured thereto by means of suitable fastenings or bolts 1, the construction thus described permitting access to Vthe interior of the casing.

Mounted transversely of the casing A and having its bearings centrally of the sides thereof is a drive shaft 2, formed with a longitudinal supply conduit 3 extending from one end of said shaft to approximately its center within the casing. The conduit 3 communicates with the pressure supply pipe A which is connected to the valve 5 secured to the removable side A by means of bolts 5, said valve being suitably formed with flanges 6 between which the usual packing is provided.

Mounted within the casing A fixedly on the shaft 2, is an elongated revoluble shell or member 7 comprising chambers 8 and 9 located at its respective end portions. Access to this shell is accomplished by the removal of the side 7 which is adjacent to the removable side A of the casing A. y

As hereinbefore premised, the pressure medium used in connection with the construction of engine to be described is steam, said steam passing from the supply conduit 3 through an opening 3 into the passage 10 in the shell 7, communicating with the chamber 8 in which is mounted an impulse wheel 11 secured on the countershaft 12, the latter having its bearings in the sides of the shell. The wheel 11 comprises a plurality of radial blades 11', the outer extremities of which are projected tangentially with respect to the rotation of the wheel, as indicated at 11, and the ends of the blades thus formed are slightly narrower than the passage 10 which is enlarged where it communicates with the chamber 8. The steam under pressure impinges against the blades 11 causing the wheel 11 to revolve, and through the medium of the pinion 13 secured to the shaft 12 at its outer extremity projecting through the revoluble member 7, which pinion meshes with a gear 1A fixed to the removable side A of the casing A, motion is transmitted to the shell, causing the same to revolve in the same direction to the movement of the wheel 11. Only a small amount of the power of the steam has been utilized up to this point and it now passes from the chamber 8 through the passage 15 into the chamber 9 at the other end of the shell 7. In this chamber a similar reaction wheel 16 is mounted on the countershaft 17, and said wheel is provided with radial blades 17 of similar construction to the blades 11. A pinion 19 is secured to the end of the countershaft 17 outside of the revoluble member 7 and meshes with the gear -lt on its opposite side from the pinion 13,

thereby assisting in an evident manner the revolution of the shell 7 by the said corresponding pinion 18. The steam now issues tangentially relative to the axis of the rotation of the member 7, from the chamber 9 through the nozzle 20 projecting from the end of the member 7, the impact thereof being directed against the abutments or projections 21 formed on the inner periphery of the casing A. Said peripheral abutments are arranged transversely of the flanges 21 integral with the casing, a plurality of pockets being formed thereby. The tendency of this last mentioned impact of the steam is to supplement or aid in the revolution of the member 7 and the spent steam exhausts through the outlet 22 in the lower portion of the casing A. Y

An important feature in the construction of my device is the mounting of the impulse wheels at opposite sides of the axis of the revoluble member, thereby producing a balancing effect which insures a smooth running action of the rotation of the revoluble member, and which is necessary in a device of this nature.

As will be most clearly seen in Fig. 2 of the drawings, the ends of the passage 15 are enlarged in a similar manner to the outlet of the passage 10, the purposeof the enlarge ments being to prevent the closure of said passages by the projections 11 of the blades 11, and those on the wheel 16.

Any desired lubricating means may be employed in connection with the mechanism herein described and I have therefore shown conventionally a lubricant reservoir 23 secured at one side of the shell 7 and provided with feeding conduits 24 extending into said shell. At a suitable point in the casing A may also be provided lubricant feeding passages 25 whereby the oil may be supplied to the bearings of the shaft 2. VAt a suitable point in the casing A an opening 26 is provided through which the lubricant may'7 be supplied to the reservoir 23 when needed. The covering 26 is fastened in place over the opening 26 by means of the bolts 26".

The outer extremity of the shaft 2 at one side of the casing is suitably provided with a pulley 27 from which power may be taken.

It will be obvious from the foregoing de- Y scription that the steam or pressure medium as controlled Vby the throttle 28 passes through the shell 7 and by means of the impulse wheels contained in the steam chambers at its opposite extremity the said shell twice utilizes the power possessed by the pressure medium and a further utilization of the power is afforded by the direction of said pressure medium against the peripheral abutments on the casing. In this manner a maximum amount of power is obtained from a small supply of pressure medium. A Y Y Any number of revoluble members may be providedon the drive shaft to increase the power desired and it will be Vunderstood that numerous other changes may be made in the details of construction without de-v Y parting from the spirit of my invention and within the scope .of the claims .hereto` appended.
